Abstract

The construction industry, recognized as one of the most hazardous sectors globally, continues to face escalating challenges, particularly in Indonesia. This sector experiences a yearly increase in workplace accidents, which significantly disrupts economic stability at both micro and macro levels. These incidents lead to substantial economic losses, reduced productivity, and increased medical and compensation costs. To address these risks, the adoption of Learning from Incidents (LFI) has emerged as a critical approach. LFI is a structured process that involves analysing and learning from past incidents to prevent future occurrences, offering a proven methodology to enhance workplace safety. However, despite its potential, the implementation of LFI in Indonesia encounters persistent obstacles. These include a weak safety culture, inadequate reporting systems, and insufficient enforcement of safety standards. Such challenges hinder the effectiveness of LFI and limit its capacity to drive meaningful improvements in construction safety. This study seeks to bridge the gap between the importance and current performance of LFI implementation in the Indonesian construction industry. The research methodology integrates a literature review, expert validation, and Importance-Performance Analysis. Through the literature review and expert validation, critical indicators for LFI implementation were identified, while the Importance-Performance Analysis assessed the alignment of expectations with actual performance as perceived by construction practitioners. Input from three construction safety experts and industry practitioners formed the basis of the analysis. The findings reveal that while Investigation Participation met or exceeded expectations, several other LFI implementation indicators–including Contextual Safety Engineering and Dissemination Reach–require substantial improvement. This consensus highlights significant discrepancies between intended outcomes and actual practices, underscoring the need for targeted strategies to enhance LFI processes. Addressing these gaps can better align LFI implementation with safety objectives, ultimately fostering a safer and more sustainable construction industry in Indonesia.

Abstract

The growth of the nickel mining industry in Indonesia, particularly in Southeast Sulawesi Province, has made this sector one of the main contributors to the Regional Gross Domestic Product (RGDP). However, the development of supporting infrastructure—especially mining haulage roads—still faces various risks that could potentially cause project delays and disrupt operational efficiency. Therefore, a systematic risk identification process is necessary to ensure that project implementation proceeds in accordance with established time, cost, and quality targets. This study aims to identify and assess risks in mining infrastructure development projects using a stakeholder-based approach. This approach is employed to gain an understanding of the risks that arise from the perspectives of the parties involved in the project. The results of this study describe the dominant risks that could potentially occur in nickel mining projects, namely opposition from the local community surrounding the project, conflicts with community organizations, denial of access to project roads, and disruption of project security due to inadequate security measures by authorities. It is hoped that these dominant risks can serve as a basis for developing effective risk mitigation strategies to support the successful and sustainable development of mining infrastructure.

Abstract

This study aims to develop a web-based AMP Information System at PT. X Jabodetabek Production Unit to reduce material waste in the asphalt production process. The existing condition shows significant deviations in material usage, including screening (9.28%), split (15.38%), asphalt (6.84%), and diesel (9.07%), which exceed the company’s waste tolerance limit of 5%. The research employs a descriptive method with both quantitative and qualitative approaches, involving archival analysis, literature review, questionnaires, interviews, and expert validation to address three research questions (RQ1–RQ3): identifying waste-related problems, developing the AMP information system, and evaluating the effect of the system on material waste reduction. The findings indicate that the main causes of material waste include frequent material rejection, mixing errors, and equipment damage, with the highest Relative Importance Index (RII) value of 0.88. The developed system features a three layer strategic dashboard monthly accumulation, daily monitoring, and real time monitoring that visualizes sensor status, temperature, material usage, and deviations from the JMF. Based on a comparative case study between two AMPs, the application of the information system reduced material waste from 4.28% to 4.14% in AMP 1 and from 4.84% to 4.79% in AMP 2. The study concludes that the development of an integrated AMP information system plays a vital role in improving operational efficiency and production quality control.

Abstract

The implementation of the procurement process for the construction services of the ATC Tower and Supporting Facilities at Perum XYZ is expected to be completed on time with the delivery of the ATC Tower infrastructure and Supporting Facilities to support optimal flight navigation services. However, in the period 2016-2023, obstacles occurred at several project locations which caused the benefits of the project development to be delayed. This study aims to analyze the dominant risk factors that affect the performance of the procurement time for the construction services of the ATC Tower and Supporting Facilities at Perum XYZ. Risk identification was carried out through literature studies and then validated by experts. Furthermore, the risks were submitted to respondents who had been involved in the procurement of construction services for the ATC Tower and Supporting Facilities at Perum XYZ and then a risk analysis was carried out by referring to the company's internal regulations related to the Company's Risk Management Policy and Guidelines. From the results of data collection and analysis, it was found that there were 5 dominant risk factors with a high risk level that affected the procurement time performance. The results of this study can be a basis for determining the development of a procurement strategy for the construction services of the ATC Tower and Supporting Facilities at Perum XYZ in improving procurement time performance

Abstract

The maintenance of cultural heritage buildings is gradually shifting from a curative approach toward preventive conservation supported by digital technologies. Although Heritage Building Information Modeling (HBIM) has been widely adopted, the resulting models are generally static and incapable of integrating real-time structural monitoring data. This study employs a qualitative case study approach combined with a literature review. The literature review was conducted to identify variables, subvariables, and indicators, which were subsequently validated by experts. In addition, benchmarking of previous frameworks was carried out to understand existing structures and methodologies. Based on these findings, a framework was developed according to the research requirements and further validated by experts to ensure its reliability and practical applicability. This study proposes a Digital Twin (DT) framework for cultural heritage buildings by integrating geometric building models, historical information, and dynamic data obtained from accelerometer sensors. The framework consists of four main layers: the information source layer, the BIM model layer, the integration layer, and the application layer for visualization and decision-making support. The framework was implemented in the Jakarta Cathedral to evaluate the integration of sensor data into the HBIM environment. Expert validation results indicate that the proposed framework provides a systematic approach to supporting preventive conservation for cultural heritage buildings with complex geometries.

Abstract

The construction industry contributes significantly to economic growth but also carries substantial environmental and social costs. Construction activities generate carbon emissions, consume natural resources, and produce large volumes of waste. Despite growing theoretical development of Sustainable Project Management (SPM) frameworks, empirical evidence on the actual level of SPM implementation in Indonesia's construction sector remains limited. This study aims to identify the factors that influence SPM implementation and measure the level of implementation as perceived by construction professionals. A quantitative survey was administered to 99 professionals across infrastructure, building, and industrial construction sectors in Indonesia. Data were collected through a Likert-scale questionnaire and analysed with descriptive statistics. Implementation was assessed against the P5 Framework (People, Planet, Prosperity, Process, Product). All seven factors in this study, including leadership, awareness, HR competence, organisational support, regulation, stakeholder engagement, and organisational culture, scored in the high category (mean range: 3.68–3.89). All five P5 dimensions also achieved high mean scores. Product (3.941) and People (3.917) were the leading dimensions. These findings indicate that Indonesian construction professionals perceive SPM implementation as consistently high across organisational and external dimensions. This study contributes empirical data to the SPM literature in the Indonesian context and provides a baseline for monitoring future implementation progress. The results identify HR competence (3.681) as the priority area for technical training investment, with direct implications for industry development programs and construction education curricula.
